Targeting tumors the natural way

...s, unleashing a potent immune response that caused immediate organ rejection. But true to natural cell recognition, the immune response occurs only when clusters of many alpha-Gal molecules are present for anti-Gal to bind with. Armed with this knowledge, Kiessling's group modified an agent known to bind ti...

Engineering the heart piece by piece

...he authors say, bioengineered cardiac tissue holds immediate promise as a way to study heart disease and its treatment in cell cultures ?and promise over the longer term as a source of new patient treatments. As part of the effort to make the leap from the lab to the clinic, U-M is applying for patent prote...

Cholera pathogen reveals how bacteria generate energy to live

...anism, Vibrio cholerae depends on resources in its immediate environment to sustain itself. Blanca Barquera, assistant professor of biology at Rensselaer and principal investigator for the project, studies an enzyme that resides in the membrane that encapsulates V. cholerae. This enzyme, known as NQR, pumps so...

Men with prostate cancer avoid radiation due to misconceptions

...is directed through the skin to the cancer and the immediate surrounding area to kill the cancer. To minimize side effects, radiation is given five days a week for several weeks. Many men with prostate cancer choose external beam radiation over other treatments because it is non-invasive, has a short recovery ...

Why don't all moles progress to melanoma?

...nst oncogenes. But she cautions that there are no immediate clinical applications for the study and additional research will be required. In future research, Soengas will attempt to determine exactly how oncogenes trigger the unfolded protein response in malignant and non-malignant skin cells. "By comparing...

Math model predicts cancer behavior

...ost aggressive and invasive tumor cells. "In the immediate term we may be diminishing tumor burden, but the long term effect is to have a much nastier tumor than there was to begin with," Quaranta said. There is anecdotal evidence, he added, to support the idea that changes to the microenvironment result in ...

New way of tracking muscle damage from radiation

...l. The researchers report that MRI can spot the immediate injury done by radiation therapy to the muscles of children undergoing radiation treatment for certain types of soft-tissue cancer. This also indicates that MRI might one day be able to help doctors predict the amount of long-term damage that radiati...

Edible coatings will be the packaging of the future

...th high added-value. This is why, amongst the most immediate projects of the research team from the Food Technology Area at the University, is the application of edible films to turrón (sweet nougat), in order to eliminate the aluminium foil currently used to protect it and so that the product would have only ...

Scientists discover way to block growth of prostate cancer cells

... men is managed by watchful observation only. The immediate goal of our research is to develop agents such as MDL to fill this unmet medical need. If MDL, or any of the other agents that we are working with, can be expanded further to treat all high-risk men, we will be delighted." ...

Researchers to develop active nanoscale surfaces for biological separations

...ecules, such as proteins," Kane said. He envisions immediate applications in genomics and proteomics, with the new approach providing several improvements over current techniques. The new surfaces could yield separations with higher resolution and greater efficiency, Kane suggested. And they can be easily f...

Firefighters face increased risk for certain cancers

...vels of increased risk. "There's a critical and immediate need for additional protective equipment to help firefighters avoid inhalation and skin exposures to known and suspected occupational carcinogens," says Lockey, professor of environmental health and pulmonary medicine at UC. "In addition, firefighter...

Nanoscale microscope sheds first light on gene repair

.... "The clusters may provide a platform for the immediate and robust response observed following DNA damage," said Bewersdorf. "Moving forward, we will analyze the localization of the H2AX clusters relative to other nuclear components." ...

Amateur boxing linked to brain cell injury

... brain functions long after boxing, rather than an immediate test performed soon after a fight. Henrik Zetterberg, M.D., Ph.D., The Sahlgrenska Academy at Göteborg University, Göteborg, Sweden, and colleagues obtained spinal fluids (via spinal tap) from 14 amateur boxers (11 men and three women, average age 2...

Down syndrome: It's not just the age factor

...s and how big the gap is between the child and his immediate preceding sibling. The research is published in Springer's journal Naturwissenschaften this week. Neuhäuser and Krackow reviewed and analysed data from 1953 and 1972 (before abortion was widespread). They found that other factors, besides the moth...

PNAS study reveals why organs fail following massive trauma

... trauma, say from a sabertooth tiger attack, meant immediate death for the primitive human. Modern man is more likely to survive severe injury caused by a car crash, gunshot or fall thanks to high-tech emergency medicine. Unfortunately, the body does not know what to do when it survives an injury that would h...

Dragonfly's metabolic disease provides clues about human obesity

...ic infection triggers an inflammatory response and immediate changes in metabolism. Unable to metabolize fat, the dragonflies accumulate fat around their muscles. This finding begs the question of whether something similar might be happening in human metabolic diseases, the root causes of which remain poorly...

Too mellow for our predatory world

...ure responded to the harassment experiment with an immediate increase in CORT levels. "Our experiments have shown that the animals increase their flight initiation distance and are able to mount a corticosteroid stress response", explains Thomas Roedl. It seems that the function of the stress axis can be ret...

Changing length of days reverses how estrogen affects aggressiveness in mice

...hort days almost immediately. It had no noticeable immediate behavioral effect on the mice living in longer day lengths. Overall, then, these studies showed estrogen increases aggression in short-day mice by working through non-genomic pathways in the brain, but the hormone decreases aggression in long-day ...

Asia's odd-ball antelope gets collared

"We must take immediate actions to protect habitat and stop and poaching for saiga horns, while improving the conditions and resources of park rangers who are spending their valuable time to protect this unique species," said Lhagva Lkhagvasuren of the Mongolian Academy of ...

Researchers discover new gene responsible for brittle bone disease

...important early step in the search for a cure, its immediate effect may be to exonerate an expanded group of parents whose children frequently appear in emergency rooms with unexplained fractures, and who may be accused of child abuse. The study was led by Brendan Lee, M.D., Ph.D., associate professor of M...
